MasterRoc MP 355 - Highly-reactive, two-component polyurethane injection resin

How does MasterRoc MP 355 work?

MasterRoc MP 355 is a two-component, solvent-free polyurethane injection resin specifically designed for stopping rapid water flow and ground stabilization.

Recommended for use in:

  • Control of high volume water ingress
  • Stabilization of fractured rock, sands and gravels, and land-fill materials
  • Void filling
  • Repair of concrete structures

What are the unique features of MasterRoc MP 355?

  • When in contact with water, the product forms a rigid foam. In the absence of water, the product reacts and forms a stiff, rubber-like material
  • Fast-reacting material where structural strength or rigidity is required

What are the benefits of MasterRoc MP 355?

  • Reacts either with or without water. This is a significant safety advantage as the material will always be cured
  • Modification of the reaction can be achieved using an accelerator and a thixotropic agent, which are supplied separately to Component A
